I'm using the AASTex package and I've been wondering how to unnumber equations (I hate numbers in equations that you don't even cite later!). So far I've tried the usual:

  • Tried to put the \nonumber line after the equation (inside the \begin{equation} and \end{equation}, of course), but it doesn't work.
  • Tried to do \begin{equation*} and \end{equation*}, but the package didn't recognize the command. I tried adding the \usepackage{amsmath} package, but this causes various features of the AASTex package to fail.

Here's a working example of my LaTeX code:


\slugcomment{This is a slug comment.}

\shorttitle{A Short title!}

\hypersetup{colorlinks=true,citecolor=blue,pdftitle={PDF title},pdfauthor={Nestor}}

\title{This is a glorious title that appears up.}

\affil{My department, my university}
\altaffiltext{1}{My affiliation.}
Let's start with Einstein's equation:
E=mc^2. \nonumber
Easy, right?

Any ideas?

As you can read on page 5 of the given documentation you can use \nonumber only in the environment eqnarray (but eqnarray should no longer be used!). Add this to your MWE:

 E=mc^2.  \nonumber

The aastex class defines its own eqnarray so I don't know if the standard "eqnarray should no longer be used" advise applies here. – Gonzalo Medina Aug 26 '12 at 3:37
I think it is important enouph to have an eye on this? My experience with aastex is pretty less (one student asked me for aastex) and I didn't test the difference between the two environments. Could be interesting ... – Kurt Aug 26 '12 at 3:50
Ugh I don't know which to accept! The two answers are great! I think I'll accept this one, because it uses "internal" definitions of aastex (plus the reference to the documentation). Thanks to both of you! – Néstor Aug 26 '12 at 4:16

You can use \[...\]:
